Many thanks. I updated the driver today, cleaned the pc board.
When it stops it does not move. Long alarm which turns off when i hit stop. Another symptom may be when homing it goes to a z axis 0 but not home on y axis. Been doing this for a couple of weeks.
Thanks for the comment. My apologies i made an error on the axis. Z axix head rIses up, x axis the laser moves to the left from its last position then beeps and stops. To move home to the back left position i need to turn off then manually move into this position. If i turn off and on the laser moves slightly right then left and beeps.
